Alumina ceramic foam filters can be widely used in the filtration of aluminum, aluminum alloys and other non-ferrous metals in the casting process. This type of filter can be placed in standard filter boxes, holding furnaces, etc. In addition to the standard specifications matching the incubator, the filter can be customized according to the size, shape and pore size required by customers.
inquiryThe alumina ceramic foam filter plate for purifying molten aluminum can effectively remove large inclusions in molten aluminum, and adsorb micron-sized fine inclusion particles, which can improve surface quality, product performance and microstructure.
Alumina filter plates are widely used in the production of aluminum profiles, aluminum foils, aluminum alloys and other fields.

There are sealing gaskets around the filter, placed between the filter and the bowl, to prevent leakage of molten aluminum through the interface. The filter adopts three different types of sealing gaskets: fiber paper material, fiber cotton material, and expanded cotton material.
The filtration efficiency of the foam ceramic board is closely related to its correct installation and use. At the same time, the conventional and necessary measures taken to reduce the generation of inclusions in the smelting, furnace treatment, casting and other process operations cannot be ignored because of the adoption of the filtration process. It is also necessary to prevent the phenomenon of re-contamination of the filtered clean aluminum liquid.
Its installation and use, in general, need to pay attention to the following aspects:
